Description

Satellite billing method, satellite billing function, billing function and storage medium

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on August 11, 2023, with application number 202311010993.6 and application name “Satellite billing method, satellite billing function, billing function and storage medium”, the entire contents of which are incorporated by reference in this disclosure. Technical Field

[0002] The present disclosure relates to the field of satellite communication technology, and in particular to a satellite billing method, a satellite billing function, a billing function and a storage medium. Background Art

[0003] As a new type of mobile communication network architecture, satellite-ground converged communication networks are becoming a global research hotspot. The 3rd Generation Partnership Project (3GPP) Non-Terrestrial Networks (NTN) project has studied the scenarios and architecture of fifth-generation mobile communication technology (5G) and satellite convergence, as well as potential issues such as mobility management and paging. It has also conducted preliminary research on satellite access billing in satellite-ground converged networks.

[0004] With the deployment of the 5G core network's Service Based Architecture (SBA), the billing system has evolved to a Converged Charging System (CCS), integrating online and offline billing functions and providing a unified interface using a service-based architecture. The rapid development of the 5G industry and the in-depth advancement of standards work have necessitated addressing satellite access billing within the CCS.

[0005] Figures 1 and 2 provide a related art converged billing architecture based on a service-oriented interface, which includes logical billing functions and an interface Bx between these functions and the billing domain (BD). The network element in which the charging trigger function (CTF) is embedded, such as the session management function (SMF), generates billing events to the charging function (CHarging function, CHF) to implement converged billing for data connections. For example, as shown in Figure 3, in the related art, the CTF generates billing events toward the CHF for converged convergent billing processing (including online and offline). The generation of the charging data record (CDR) is performed by the CHF as the charging data function (CDF) and transferred to the charging gateway function (CGF). Finally, the CGF creates CDR files and forwards them to the BD.

[0006] 5G functional modules and billing architecture are based on service-oriented interfaces. In related technologies, regardless of whether satellite access is in transparent or regenerative mode, when a satellite service customer (such as user equipment (UE), IoT devices, broadband vehicle-mounted or fixed terminals, etc.) accesses, the CTF cannot identify that this billing event is based on satellite access, resulting in losses for the satellite mobile network operator (SMO) or satellite service provider (SSP).

[0134] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0135] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0136] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0137] In order to solve the problems of terminal access and data services under dynamic beam hopping and realize the configuration of beam hopping resources, the embodiment of the present disclosure proposes a satellite billing method, which can realize the flexible configuration of beam hopping resources in a 5G-based satellite communication scenario, improve the efficiency of beam scheduling and management, and thus provide support for improving resource utilization and system communication capacity.

[0138] The embodiments of the present disclosure provide a satellite billing method that can implement satellite-related service billing when a terminal accesses a terminal via a satellite. FIG4 provides a flow chart of the above method when applied to a satellite billing function, wherein the satellite billing function can specifically be a charging trigger function (CTF). The CTF can be independently deployed in the core network or in one or more core network elements, for example, in an access and mobility management function (AMF) or a short message service function (SMSF). The satellite billing function can also be a charging enablement function (CEF) in the related art. The CEF can generally use management services or services exposed by network functions.

[0139] As shown in Figure 4, the method includes:

[0140] Step 401: Determine satellite billing information related to the terminal.

[0141] Here, the satellite billing function can determine the satellite billing information related to the terminal when the terminal accesses the network via satellite. The terminal can specifically be a user equipment (UE), an Internet of Things device, a broadband vehicle or fixed terminal, etc. Based on different billing requirements, the satellite billing information related to the terminal can be determined, which can specifically include at least one of the following:

[0142] (1) The satellite access type of the terminal. For example, based on the orbital altitude of the satellite to which the terminal accesses, it can be divided into low earth orbit (LEO) satellites, medium earth orbit (MEO) satellites, geosynchronous earth orbit (GEO) satellites, and other satellites (OTHERSAT). For example, the AMF can determine the radio access technology (RAT) type where the terminal resides based on the global RAN node ID associated with the N2 interface and the tracking area indicated by the next generation radio access network (NG-RAN). The AMF determines the RAT type of the new radio (NR) satellite access, namely NR (LEO), NR (MEO), NR (GEO), and NR (OTHERSAT). When the terminal accesses NR using satellite access, the type of satellite access NR, namely the satellite access type, will be displayed on the N2 interface.

[0143] (2) Terminal location information: The terminal location information includes at least one of the following: the current location of the terminal, a Presence Reporting Area (PRA) identifier, and an indicator of whether the terminal is inside or outside the PRA.

[0144] (3) Tracking Area Identifier (TAC) information of the terminal's NTN.

[0145] (4) Satellite-related parameters, for example, the satellite-related parameters include one or more of the following parameters: satellite name, satellite catalog number, orbital altitude, orbital plane, ephemeris information, destination, and country. The ephemeris information may specifically include at least one of the following information:

[0146] -Semi-major axis;

[0147] -Eccentricity;

[0148] -Argument of periapsis;

[0149] - Longitude of ascending node;

[0150] -Inclination;

[0151] -Mean anomaly at epoch time.

[0152] (5) Resource usage information, such as the amount of service data sent and received by the terminal;

[0153] (6) Service duration, specifically, the time interval from when a terminal establishes a Protocol Data Unit (PDU) session to when it releases the PDU session.

[0154] In some embodiments, the terminal-related satellite billing information may also include more billing auxiliary information, such as a Quality of Service (QoS) flow usage report, which may specifically include at least one of the following information: QoS flow identifier (Qos flow ID, QFI), QoS flow start time, end time, uplink traffic, downlink traffic, etc.

[0155] Step 402: Send the satellite billing information to a charging function (CHF).

[0156] Here, the satellite billing function sends the satellite billing information to the CHF so that the CHF can create or update a charging data record (CDR) based on the satellite billing information, thereby implementing billing for satellite-related services. Specifically, the satellite billing function can send the satellite billing information to the CHF via the Hchf interface. The satellite billing information can be carried in a Charging Data Request message.

[0157] Step 403: Receive the charging data response message sent by the CHF.

[0158] Here, after creating or updating the CDR, the CHF may send a Charging Data Response message to the satellite charging function. The message is used to indicate that the CHF has created or updated the CDR. The message may carry the result of the CHF processing the CTF request.

[0159] Through the above steps, the embodiment of the present disclosure uses the satellite billing function to collect relevant billing information when the terminal is accessed via a satellite, obtains the terminal-related satellite billing information and sends it to the CHF, so that the CHF can implement satellite-related service billing based on the terminal-related satellite billing information.

[0160] Based on different billing requirements, the satellite billing function can collect terminal-related satellite billing information. The following example illustrates this.

[0161] For example, if a terminal needs to be billed for accessing the network via satellite, the satellite billing function can determine satellite billing information related to the terminal when determining that the terminal accesses the network via satellite. Specifically, the satellite billing function can determine whether the terminal accesses the network via satellite based on one or more of the satellite access indication flag (the satellite access indication flag is a flag used to indicate whether the terminal accesses the network via satellite), the wireless access type, and the terminal's location information. When determining that the terminal accesses the network via satellite, the satellite billing information related to the terminal can be determined based on information such as resource usage information and / or service duration of the terminal. The satellite billing information may include information such as resource usage information and / or service duration, and may also include other auxiliary billing information. In this example, the satellite billing function can be a charging trigger function (CTF), which can be deployed in an AMF so that the CTF can obtain the satellite billing information directly from the AMF; or, the satellite billing function can be a charging enabling function (CEF), which determines the satellite billing information related to the terminal by interacting with the AMF and / or the Operation Administration and Maintenance (OAM).

[0162] For another example, when a terminal accesses via satellite, if location reporting needs to be charged, the satellite billing function may determine the satellite billing information related to the terminal based on the terminal location information and / or the presence reporting area (PRA) information of the terminal, wherein the satellite billing information includes the terminal location information and / or PRA information, and the PRA information includes at least one of the following: a tracking area list, a PRA identifier, and an indicator of whether the terminal is inside or outside the PRA. The terminal location information may include at least one of the following: the current location of the terminal, a PRA identifier, and an indicator of whether the terminal is inside or outside the PRA. In this example, the satellite billing function may be a CTF deployed in the AMF, so that the CTF can obtain the satellite billing information directly from the AMF; or, the satellite billing function may be a CEF, and the CEF can determine the satellite billing information related to the terminal by interacting with the AMF and / or OAM. The satellite billing function may also be a CTF deployed in the SMF or SMSF.

[0163] For another example, when the terminal accesses the network via satellite, if the Short Message Service (SMS) needs to be charged, the satellite billing function can determine whether the short message sent by the terminal is sent based on the satellite. For example, if the short message service is used when the terminal accesses the network via satellite, it can be determined that the short message sent by the terminal is sent based on the satellite. In the case where the short message sent by the terminal is sent based on the satellite, the satellite billing function determines the satellite billing information related to the terminal, and the satellite billing information also includes: indication information for indicating that the short message is sent based on the satellite. In this example, the satellite billing function can be a CTF deployed in a Short Message Service Function (SMSF), so that the CTF can obtain the satellite billing information directly from the SMSF; or, the satellite billing function can be a CEF, and the CEF can determine the satellite billing information related to the terminal by interacting with the SMSF and / or OAM.

[0164] For another example, when a terminal accesses via satellite, if the terminal's Protocol Data Unit (PDU) session needs to be billed, the satellite billing function can determine the terminal-related satellite billing information when it detects that the terminal initiates a PDU session through the NTN and the PDU session and / or the service data in the PDU session needs to be billed. The satellite billing information also includes: relevant information about the PDU session. In this example, the satellite billing function can be a CTF deployed in a Session Management Function (SMF), so that the CTF can obtain the satellite billing information directly from the SMF; or, the satellite billing function can be a CEF, and the CEF can determine the terminal-related satellite billing information by interacting with the SMF and / or OAM.

[0165] Referring to FIG. 5 , the satellite billing method provided in the embodiment of the present disclosure, when applied to CHF, includes:

[0166] Step 501: Receive satellite billing information sent by a satellite billing function.

[0167] Here, the CHF may receive a Charging Data Request message sent by the satellite charging function and obtain the satellite charging information from the message. Specifically, the satellite charging information may include at least one of the following:

[0168] (1) Satellite access type of the terminal;

[0169] (2) Terminal location information;

[0170] (3) Tracking area identification (TAC) information of the non-terrestrial network (NTN) of the terminal;

[0171] (4) Satellite related parameters;

[0172] (5) Resource usage information;

[0173] (6) Business duration;

[0174] The satellite-related parameters include one or more of the following parameters: satellite name, satellite catalog number, orbital altitude, orbital plane, ephemeris information, destination, and country. The terminal location information includes at least one of the following: current location of the terminal, PRA identifier, and an indicator of whether the terminal is inside or outside the PRA.

[0175] Step 502: Create or update a CDR based on the satellite billing information.

[0176] Here, in step 502, the CHF creates or updates the CDR according to the information included in the satellite billing information.

[0177] For example, if the satellite billing information indicates that the terminal accesses the network via satellite, and the satellite billing information includes resource usage information and / or service duration of the terminal, the CHF creates a CDR based on the service resource usage information and / or service duration of the terminal. In some embodiments, if the satellite billing information also includes auxiliary billing information, the CHF may further create a CDR based on the auxiliary billing information to achieve more accurate accounting and billing.

[0178] For another example, when the satellite billing information indicates that the terminal accesses the network via a satellite, and the satellite billing information includes terminal location information and / or PRA information, a CDR is created for the billing event of the location report; wherein the PRA information includes at least one of the following: a tracking area list (TrackingAreaList), a PRA identifier, and an indicator of whether the terminal is inside or outside the PRA.

[0179] For another example, the satellite billing information may further include instruction information for instructing the sending of a short message via satellite. In this case, if the satellite billing information indicates that the terminal accesses the network via satellite and the satellite billing information also includes instruction information for instructing the sending of a short message via satellite, the CHF creates a CDR for the billing event of the terminal sending the short message via satellite.

[0180] For another example, the satellite billing information may further include information related to the PDU session. In this case, if the satellite billing information indicates that the terminal accesses the network via satellite and the satellite billing information also includes information related to the PDU session, the CHF creates or updates a CDR for the PDU session.

[0181] In an embodiment of the present disclosure, the CHF may determine whether the terminal accesses the network via satellite based on one or more of the following information: the terminal's satellite access type, terminal location information, TAC information of the terminal's NTN, satellite-related parameters, and the like in the satellite billing information. For example, if the terminal's satellite access type is LEO, MEO, GEO, or OTHERSAT, it may be determined that the terminal accesses the network via satellite.

[0182] Step 503: Send a billing data response message to the satellite billing function.

[0183] Here, the CHF may send a Charging Data Response message to the satellite charging function to indicate that the CDR has been created or updated.

[0184] To help better understand the above embodiments, the specific implementation of the embodiments of the present disclosure is further described below with reference to the accompanying drawings in different billing scenarios through the interaction between functional entities.

[0185] Example 1: Mobility and Connectivity Charging

[0186] Refer to Figure 6, where CTF is deployed on AMF. This example includes:

[0187] In steps 601 to 603, the UE accesses the New Radio (NR) system through the NTN and sends a registration message to the network.

[0188] Step 604: UE initiates a registration process, for details, please refer to related technologies.

[0189] Step 605: After the UE successfully registers, the AMF sends a registration acceptance message to the UE.

[0190] In step 606 (optional), the CTF may need to obtain satellite-related parameters from the OAM or Unified Data Management (UDM) entity.

[0191] Specifically, the satellite-related parameters include: one or more of: satellite name (name), satellite directory number (norad id), orbit altitude, orbit plane, ephemeris information, destination (destination), country (owner), and the like.

[0192] In step 607, the AMF (CTF) determines that the access is initiated by satellite based on one or more of the following information: the satellite access indication flag of the terminal (for example, the AMF generates and stores the flag according to the access information of the terminal), the radio access type RAT (such as "NR(LEO)", "NR(MEO)", "NR(GEO)", "NR(OTHERSAT)", etc.), and the location information of the UE. The charging trigger function CTF collects the satellite charging information and sends the satellite charging information to the CHF through a Charging Data Request message.

[0193] Satellite billing information includes at least one of the following:

[0194] - Satellite access type: such as RAT ("NR(LEO)", "NR(MEO)", "NR(GEO)", "NR(OTHERSAT)", etc.

[0195] -UE location information and NTN Tracking Area Identifier (TAI) information, such as:

[0196] servingPLMN PLMNIdentity,

[0197] tACListInNRNTN TACListInNRNTN,

[0198] uELocationDerivedTACInNRNTN TAC

[0199] - the satellite-related parameters in step 606;

[0200] Step 608: The CHF generates a charging report (CDR) based on the received satellite charging information.

[0201] Step 609: CHF reports a Charging Data Response message to AMF. Example 2: Satellite Position Report Charging (Post Event Charging)

[0202] As shown in Figure 7, CTF is also deployed on AMF. This example specifically includes:

[0203] In step 701, a new N2 connection is established between the Next Generation Radio Access Network (NG-RAN) and the AMF. Location reporting charging is activated in the AMF charging profile. There may be a status reporting area list. The "terminal status" in the status area list PRA describes whether the terminal enters or leaves the PRA.

[0204] In step 702, the AMF sends a Location Reporting Control to the NG-RAN according to the startup procedure described in the related art, indicating that the UE's location change or the reporting area where the UE is located needs to be reported.

[0205] In step 703, the AMF receives a location report from the NG-RAN, which includes the UE's current location and the potential PRA area. When the UE uses NR satellite access, the cell and TAI reported by the NG-RAN refer to the fixed cell and fixed TA of the UE's geographic location.

[0206] In step 704, if location reporting charging is activated in step 701, the AMF (CTF) determines that the access is initiated by satellite based on one or more of the terminal's satellite access indication flag (for example, the AMF generates and saves the flag based on the terminal's access information), the radio access type RAT (such as "NR (LEO)", "NR (MEO)", "NR (GEO)", "NR (OTHERSAT)", etc.), and the UE's location information. The AMF (CTF) collects satellite-related information about the charging event.

[0207] In some embodiments, the CTF may need to obtain satellite-related parameters from the OAM or UDM. Satellite-related parameters include one or more of the following information: satellite name, satellite directory number (norad id), orbital altitude, orbital plane, ephemeris information, destination, and owner.

[0208] The AMF (CTF) sends a Charging Data Request message to the CHF, which contains the current UE location and the initial status of the subscribed PRA (Presence Reporting Area).

[0209] Step 705: CHF creates a CDR for this location report.

[0210] In step 706, the CHF confirms the creation of the CDR by sending a Charging Data Response message to the AMF.

[0211] Step 707: According to the AMF standard provided in step 702, a change in the UE location or presence status reporting area occurs.

[0212] Step 708: AMF receives the updated location report sent by NG-RAN.

[0213] In step 709, the AMF sends a Charging Data Request message to the CHF, which includes the new UE location, the PRA identifier, and an indication of whether the UE is inside or outside the status reporting area (if any).

[0214] In step 710, the CHF creates a CDR for the updated location report.

[0215] Step 711: CHF confirms by sending Charging Data Response to AMF.

[0216] Example 3: Satellite Short Message Service Billing

[0217] As shown in Figure 8, the CTF is deployed on the AMF. In this example, the interaction between the SMSF and the CHF is essentially the interaction between the SMSF (CTF) and the CHF. This example specifically includes:

[0218] Step 801, the initialization process between the UE and the SMSF, can be referred to related technologies and will not be repeated in this example.

[0219] Step 802: The SMSF receives an SMS Submit message sent by the UE.

[0220] In step 803, the SMSF determines whether the short message is sent via satellite based on at least one of the following indication information:

[0221] a) Short Message Service Type (SMServiceType): The short message service type adds an indication bit for short messages sent via satellite (VAS4SMS_SHORT_MESSAGE_NTN). Through this indication bit, it can be determined that the short message is sent based on satellite.

[0222] b) Satellite access type: e.g., RAT ("NR(LEO)", "NR(MEO)", "NR(GEO)", "NR(OTHERSAT)", etc.

[0223] c) UE location information and NTN Tracking Area Identifier information:

[0224] servingPLMN PLMNIdentity,

[0225] tACListInNRNTN TACListInNRNTN,

[0226] uELocationDerivedTACInNRNTN TAC

[0227] d) Satellite parameters obtained from OAM (refer to the above example);

[0228] In response to the received Mobile Originate (MO) short message, the SMSF sends a Charging Data Request [Event] message to the CHF. Parameters related to the Charging Data Request message also include the information of whether the short message is satellite-based.

[0229] Step 804: CHF creates a call record (CDR) for the short message.

[0230] Step 805: CHF confirms by sending a charging data response [Event] to SMSF.

[0231] Step 806: The SMSF returns a short message submission answer (SMS Submit Answer) and provides a corresponding result: whether the SMSF successfully receives the short message (SMS).

[0232] Step 807: forward the SMS according to the applicable process, which will not be described in detail here.

[0233] Example 4: Satellite data service billing

[0234] Refer to Figure 9. In this example, CTF is deployed in SMF. This example includes:

[0235] In step 901, the UE initiates a PDU session connection process through the NTN. For details, please refer to related technologies and will not be described here.

[0236] Step 902: When a PDU session or a service data flow in a PDU session needs to be charged, the CTF determines that this is a data flow accessed by a satellite and collects satellite-related charging information.

[0237] In step 903 (optional), the CTF may need to obtain satellite-related parameters from the OAM or UDM. Satellite-related parameters include one or more of the following: satellite name, satellite directory number (norad id), orbital altitude, orbital plane, ephemeris information, destination, and owner.

[0238] In step 904, the SMF (CTF) determines that the access is initiated via satellite based on one or more of the following information: the satellite access indication flag of the terminal, the radio access type RAT (such as "NR(LEO)", "NR(MEO)", "NR(GEO)", "NR(OTHERSAT)", etc.), and the location information of the UE. The charging trigger function CTF collects satellite charging information and sends the satellite charging information to the CHF through a charging request message (Charging Data Request).

[0239] Satellite billing information includes at least one of the following:

[0240] - Satellite access type: RAT ("NR(LEO)", "NR(MEO)", "NR(GEO)", "NR(OTHERSAT)");

[0241] -UE location information and NTN Tracking Area Identifier information:

[0242] servingPLMN PLMNIdentity,

[0243] tACListInNRNTN TACListInNRNTN,

[0244] uELocationDerivedTACInNRNTN TAC

[0245] - Satellite related parameters in step 903;

[0246] Step 905: CHF opens the billing statement (Open CDR) and performs billing.

[0247] Step 906: CHF sends Charging Data Response to SMF.

[0248] Step 907: AMF sends a message to SMF: SM Request with PDU Session Update Requst N2 SM information, requesting a PDU session update.

[0249] In steps 908 to 910, the CTF sends a Charging Data Request message to the CHF, and the CHF updates the CDR.

[0250] Step 911: SMF sends a message to AMF: SM Request with PDU session Update Response to AMF, indicating that the PDU session has been updated.

[0251] Example 5: Satellite data service billing initiated by CEF

[0252] According to the architecture defined in the relevant technologies, the CEF can use both management services and services exposed by network functions. As shown in Figure 10, in Example 5, the CTF in Example 1 is replaced with the CEF. The specific steps of Example 5 are similar to those in Example 1, except that the CEF can obtain the required information from the AMF and OAM and send the satellite service charging request message to the CHF.
